TOTO THP3339 – Frequently Asked Questions
1) What thread size is the TOTO THP3339 screw?
THP3339 is an M3 x 4 screw, meaning a 3 mm metric thread with a 4 mm length. It is a metric fastener, so it will not thread into an imperial (inch) tapped hole even if the hole looks close in size.
2) Is TOTO part THP3339 a complete trim part or just a fastener?
It's a fastener only, a single M3 x 4 screw, not an assembly. If you're replacing a faucet or flush valve component and need the body as well, order that part separately; THP3339 covers just the screw.
3) What part number do I give my supplier to order the TOTO M3 x 4 screw?
Order it as TOTO THP3339. That's the manufacturer part number for the M3 x 4 screw, and it's the only number you need, there are no size or finish options to specify.
4) Can I substitute a hardware-store screw for TOTO THP3339?
Any substitute has to match M3 thread and 4 mm length, which is a short, small-diameter metric screw not always carried in general hardware assortments. Head style and finish on the genuine TOTO part are matched to the fixture it came from, so on a visible bath or washroom fitting the OEM screw is the safer call.
